穿梭效应导致锂硫电池（LSBs）充放电性能衰减、寿命短，阻碍其成功进入商业化。穿梭效应的抑制策略可阻止聚硫负离子移动和减少可溶性Li₂Sx浓度。前者对穿梭效应的抑制存在饱和现象，因此在优化锂硫电池正极材料中，引入过渡金属催化剂加速聚硫化锂的转化是进一步抑制穿梭效应、提高电池寿命的可行方案。通过优化碳复合材料设计制备了氧化亚锰（MnO）@空心碳球复合材料，两面三点（物理：多孔笼状结构的阻碍；化学：极性材料共价吸附和催化剂加速多硫化锂转化）协同抑制穿梭效应。结果表明，该优化材料能有效提升锂硫电池充放电性能、改善循环寿命，且倍率性能良好。在0.5 C倍率下，其初始放电比容量达到1009 mA·h/g，经过200次循环之后，其比容量为853 mA·h/g，容量保持率达到84.5%。

The shuttle effect of polysulfides cause lithium-sulfur batteries (LSBs) to have a degraded charge and discharge performance, a short service life and a poor cyclic stability, hindering LSBs to be commercialization.To suppress the shuttle effect, two strategies have been developed, including restraining the movement of S_x^2- and reducing the concentration of Li₂S_x.However, there exists saturation phenomenon in the suppression of shuttle effect by using the former strategy.Therefore, it is favorable for further suppressing the shuttle effect by adding transition metal catalysts for accelerating the conversion of polysulfides.MnO@hollow carbon sphere (MnO@C), an improved composite for suppressing the shuttle effect, is designed and prepared through optimizing carbon composites.It can suppress the shuttle effect through the synergy between physical and chemical effects.It is proved by the results that the optimized composite can effectively help LSBs to improve the charge/discharge performance, the cycle property and the rate capability.The initial discharge specific capacity of the LSBs reaches 1, 009 mAh·g^-1 at 0.5 C.After 200 cycles, the specific capacity of the LSBs is 853 mAh·g^-1, indicating that the capacity retention ratio achieves 84.5%.
